Left-handed pitching prospect Tyler Anderson has yet to start throwing and is still waiting to get clearance to begin throwing at Rockies' camp, reports the Denver Post on Wednesday.

Anderson suffered a stress fracture in his left elbow in 2013. The 2011 first-round pick bounced back with a 7-4 record along with a 1.98 ERA in 23 starts for Double-A Tulsa before his season was cut short during the postseason due to soreness in the same elbow. Now Anderson is taking a more cautious approach in his recovery, and remains without a timetable.

"If it was up to me, I'd throw right now, but I have to be smart," Anderson said. "We want to takes it extra slow and make sure it never happens again."

The Rockies announced Thursday starting pitcher prospect Tyler Anderson will not be ready to pitch when spring camp opens Feb. 21, per The Denver Post.

"We are taking our time with this and we think it's best to take a conservative approach," trainer Keith Dugger said. "He will participate in camp, but he won't pitch. He'll take part in PFP (pitchers' fielding practice) and other activities. We think the prognosis is good for the long term."

Anderson had his season end in the Double-A playoffs last season due to elbow soreness. General manager Jeff Bridich said in December that Anderson's rehabilitation was going well and said it was "conceivable" he would be in the mix for a roster spot this spring. However, his slow recovery from the elbow injury could hinder his chances of making the opening day roster.

Anderson had a great year in 2014 before getting hurt. He went 7-4 with a 1.98 ERA in 23 starts for Double-A Tulsa. The 2011 first-round pick is 23-10 with a 2.39 ERA in 59 minor-league starts.

"We are going to do what's best for Tyler's long-term future with our club," Bridich said of having no specific timetable for Anderson.

Rockies promising pitching prospect Tyler Anderson was removed from the Wednesday night playoff game for Double-A Tulsa with elbow soreness, though the move was greatly precautionary, per the Denver Post.

Anderson was taken out after pitching just three innings. He is coming off a regular season in which he compiled a 7-4 record, 1.98 ERA and 106 strikeouts in 118 1/3 innings.
